Clinical and instrumental risk factors for epileptic seizures in patients after traumatic brain injury

Year: 2016, volume 12 Issue: №3 Pages: 366-370
Heading: Neurology Article type: Original article

Organization: Samara State Medical University
Summary:

The aim: analysis of factors influencing the risks of posttraumatic epilepsy (РТЕ). Materials and Methods. The study involved 71 patients with traumatic brain injury of moderate and severe with emerging after her epileptic seizures. Among the subjects was 56 (78.9%) males and 15 (21.1%) females. The average age of the subjects was 65.6±10,3 years. The control group was 25 (71.4%) male patients and 10 (28.6%) females. The average age of the patients was 54.4.±9.3 years. Analysis of factors influencing the risks of РТЕ use nonparametric Spearman correlation and multivari-ate analysis of variance. Results. Among the many factors to be statistically significant risk factors for РТЕ was alcohol intoxication at the time of trauma 27 (38,0%), relative to the control group 2 (5.7%) p

The analysis of transition probability of monofocal clinically isolated syndrome to clinically defnite multiple sclerosis

Year: 2012, volume 8 Issue: №2 Pages: 432-435
Heading: Neurology Article type: Original article
Authors: Zakharov A.V., Poverennova I.E., Khivintseva E.V., Greshnova I.V., Gendullina E.A.
Organization: Samara State Medical University
Summary:

The goal of the research is to investigate the frst attack of demyelinated disease with an affection of one of functional systems. To assess the factors affecting the rate of transition monofocal clinically isolated syndrome (CIS) into a reliable multiple sclerosis. The structure of monofocal CIS was studied in case of 102 observations. The conversion of monofocal CIS in clinically defnite multiple sclerosis (CDMS) was retraced. The results of clinical and instrumental methods (magnetic resonance imaging — MRI and multimodal evoked potentials — MEP) were studied. Clinical and instrumental identifed markers of high transition probability monofocal CIS to CDRS were found. Early age of CIS formation and a large number of demyelination foci on MRI are the risk factors for the development to CDRS.

Facilities of different methods of automatic recognition of sleep stages

Summary:

The gole of the research is to consider the information content in application of different fractal methods of deterministic chaos to the automated recognition of sleep phases in computer electroencephalogram (EEG). The Hurst normalized range method, the method of calculating of Grassberger — Procaccia correlation integral and the approximated entropy method are used during the research. The research reveals that a hypnogram can be obtained. It’s possible if appropriate parameters of the methods indicated above are used, as well as the necessary normalization of the original data and averaging the results. A hypnogram has a total coincidence of defned sleep phases for half of the epochs which are recorded on EEG. Current methods of automatic recognition of sleep stages based on the deterministic chaos allow to reduce signifcantly the time of interpretation of polysomnographic recording and reduce the number of channels through which parameters of sleep are registrated.
